In France September 9, 1932 6 Claims. (01. 259-5) It is an essential condition that the dimensions persion to be obtained.

For instance, in the derivatives,

results to be obtained.)

The refining Will therefore mixing apparatus is bette refining of petroleum in the degree of dispersion.

According to my invention, the surfaces along which Under these not running, it to replace compression is low.

Preferred embodiments tion will be hereinafter d be the easier as the r adapted to variations of the present invenescrib to the accompanying drawing,

way of example, and in w hlCh ed with reference given merely by angles to the surface of disk I.

The balls 4, which are shaft 2 increases.

In the embodiment of Fig.- 3, the upper face of disk I is given the shape of a cone the angle at the apex of which is very large. The inner face of ring 3- is given the shape of fluid substances which comprises in combination emulsify together.

'tions of which are fluid substances adapted to the simultaneous use of balls of different diameters. These balls then form a series of concentric circular rows providing passages of gradually decreasing dimensions between them for the passage of the constituents of the mixture or of the emulsion, the velocities of the relative displacements of the walls of these passages increasing inversely to their diameters. It follows that the mixing or ually, which may constituents that be interesting inthe case of are difficult to mix or to ducing the various constituents successively, at the desired phase of the mixing operation. Thus, in the embodiment of Fig. 4, two of the constituents of the mixture are admitted, through conduits 5 and 5 respectively, into the central part of the machine, while a third constituent is fed, through conduit '1 between the two circular rows of balls shown in the drawing.

While I have described what I deem to be practical :and efficient embodiments of my. invention, it should be well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, and form of the parts without departing from the principle of my invention as comprehended within the scopeof the appended claims.

What I claim is:

1. A machine for mixing together at least two two coaxial organs adapted to rotate with respect to each other about their common axis, a plurality of balls each in contact with both of these organs, and means for feeding the substances to be mixed together onto the central portion of one of said organs, the surfaces of said organs that contact said balls consisting of surfaces of revolution the respective axial sectwo lines converging toward their peripheries, whereby the balls are applied against said surfaces merely by their weight and the action of centrifugal force, the common axis of said surfaces being vertical with the lower surface conical and the upper surface also conical and extending in the same direction but with a smaller angle at the apex of the cone, the balls being of different sizes and automatically positioning themselves in a radial direction according to their diameter.

2. A machine for mixing together at least two which comprises in combination two coaxial organs adapted tov rotate with respect to eachother about their common axis, a

. plurality of balls each in contact with both of these organs, and means for feeding the substances to be mixed together onto the central portion of one of said organs, the surfaces of said organs that contact said balls consisting of surfaces of revolution the respective axial sections of which are two lines converging toward 'their peripheries, whereby the balls are applied against said surfaces merely by their weight and the action of centrifugal force and means for feeding a substance to be mixed at an intermediate point of the radius of said organs.

3. A machine for mixing together at least two fluid substances which comprises in combination two coaxial organs adapted to rotate with respect to each other about their common axis, a plurality of balls each in contact with both of these emulsifying takes place grad- This also permits of introorgans, and means for feeding the substances to be mixed together onto the one of said organs, the surfaces of said organs that contact said balls consisting of surfaces of revolution the respective axial sections of which are two lines converging toward their peripheries, whereby the balls are applied against said surfaces merely by their weight and the action of centrifugal force, said balls being of diiferent sizes forming a plurality of circular rows and central portion of means for feeding a substance to be mixed between two of said rows of balls.

4. A machine for mixing together at least three fluid substances, which comprises in combination, two coaxial organs adapted to rotate with respect to each other about their common axis,

- the respective surfaces of said organs that face each other consisting of surfaces of revolution the respective axial sections of which are two lines converging toward the periphery, a set of balls of a given diameter arranged to be in contact with both of these surfaces, at least another set of balls of a different diameter arranged to be also in contact with both of these surfaces, means for feeding two of the substances to be mixed together onto the central portion. of one of these organs, and means for feeding a third substance to be mixed with the two first mentioned ones between the sets of balls of different diameters. a

5. A machine for mixing together at least three fluid substances, which comprises in combination, a rotary plate, an organ mounted above said plate in coaxial relation therewith adapted to rotate with respect thereto, the under surface of this organ that is located opposite the upper face of said plate consisting of a surface of revolution the axial section of which is a line converging toward the periphery of said plate, a set of balls of a given diameter resting on said plate so as to be in contact with said surface of revolution, another set of balls of a different diameter resting on said plate so as to be also in contact with said surface of revolution, means for feeding two of the substances to be mixed together onto the a'rotary plate,'an organ mounted above said plate in coaxial relation therewith 'adapted'to rotate with respect thereto about their common axis, the under surface of said organ that is located opposite the upper face of said plate consisting of a surface of revolution the axial section of which is a stepped line converging toward the periphery ofsaid plate, a set of balls of a given diameter resting on said plate so as to be in contact with said surface of revolution along a step thereof, another set of balls of a different diameter resting on said plate so as to be in contact with said surface of revolution along another step thereof, means for feeding two of the substances to be mixed together onto the central part of said plate, and means for feeding a third fluid substance to the two first mentioned ones between the sets of balls of different diameters.
